2002 Silverado, remote start and 55LW

Hi, I've read through most of the forums looking for information on the DEI 55lw bypass module and haven't found anything close to my situation. I am in process of installing a DesignTech Ready Remote Deluxe starter in my 2002 Silverado and am using a DEI 55LW to bypass the passlock II system. I've made all the connections, except for the BLUE status wire that comes off the 555LW. I tried connecting it to the "Key Sensor" wire in the ignition harness as well as leaving it alone. The car cranks almost starts then dies. I think it is the bypass that is causing the issue. Where am I suppose to connect this BLUE wire off the 555LW? The directions say to connect it to the BLACK/ blue or Blue status wire coming off the starter. There isn't a status wire. Would grounding this wire do it? I would appreciate any help. I told my wife when she gave this to me, that I have done this before and it is a pain to install. I've spent over 8 hours trying to work on it today alone. Thanks, Tony

First, can you start the truck with the key? If you cannot, leave the key in the switch turned to the run position and leave it on for ten minutes. This will reset the passlock system, allow the vehicle to start, and allow you to continue with the installation. DEI calls their negative when activated output a 'status output' this wire provides a low current negative when the remote starter is activated. Your designtech system should have a wire that behaves in the same fashion, you would use that. Since you did not make mention of the model number of your system I could not look up your exact model, however I noticed on a few manuals that their is an 'ingition 3' low power output that you could use to the blue wire of the 555lw. You cannot just ground the wire, because this would cause the 555lw to be on at all times. Hope this helps.

thanks for the input. I can start the truck with the key. That's why i think it must be a passlock issue. I keep getting a 6 code on the diagnostics. Though at times I was getting a 3 code too. I am installing the Deluxe Ready Remote from Designtech # 23927. The Silverado doesn't have an ignition 3 wire. I tired a couple of different configurations with the BLUE wire. I really appreciate your help. Tony

I think you misunderstood, the ignition 3 output I was referring to is an output from the remote starter that provides a low current negative output while the remote starter is operating. On your 23927 that wire is a BLACK/ white. Take a look at your manual, read the description for this wire, it is number 16 on page 4 and described in better detail on page 6 section 3. This wire is the recommended output for controlling a factory anti-theft bypass module. Hook it to your blue wire.

Thanks, I can't tell you how many times I read and reread the instructions looking for something that I missed. I'll try that. My dash is completely apart right now and I need my truck for work tomorrow. Tony

Hi, I just tried connecting the two wires. I checked all the other connections, and reinitialized the unit. It won't start still. Engine cranks, seems to turn over then dies. I get the same code. 6 flashes. On page 21 and on page 1 of the trouble shooting guide there are descriptions of what the issue could be. Could it be low battery voltage? How do I check for that? I have the switches inside the unit set for Ign #2 to be on, Tach is off, Gear is off too. Not sure how to connect to the Tach if I had to. I tried looking under the hood for the EMC but had troouble locating it. Thanks, Tony

Hi, I looked over all the wiring again and tested with the multitester. I believe I have the right wires, except for the Pink wire coming from the 555LW. It says to connect it to the large guage pink wire coming from the Direct remote starter that connects to the main ignition. On the DesignTech remote starter the wire that connects to the main ignition ( I assume is ignition 1) is a blue wire. I am getting hte same result no matter what I try. Car cranks, almost starts then dies. I used the multi on the battery, registering more then 12 V. I can still start the car with the key. After every attempt I start the car with the key, to let the 555LW relearn the code too. This is driving me nuts. I may end up ripping out all the work that I done to this thing. I appreciate your help more then you can imagine. Tony

Hi, After doing many searches in the forums, I went back out to the truck and noticed acouple of things that might help; 1. the security light on the dash blinks after the truck tries to start. In between start tries the battery light is on display. I believe this means that the 555LW isn;t bypassing the Passlock II. Seems to be connected correctly though... I've checked all the connections 2. tried extended crank and super crank (tachless mode) seems to want to start but doesn't. 3. should I bother with connecting to the Tach if it is the passlock system? I've read about a PURPLE / white wire that i could use, or a wire off one of the injectors. 4.Should I stay with the 555lw? I have programmed it a couple of times, letting the engine run for a couple of miinutes not the 5 seconds that the manual says. I appreciate any help anyone could help me with this. My wife isn't exactly thrilled by this. Thanks, Tony

Make absolutely sure that you are on the correct ignition wires. It sounds to me as if you may be powering the accessory wire as an ignition "In between start tries the battery light is on display", the battery light indicator will come on with the key in the first forward position, which on this truck is the accessory position. The remainder of the indicators should be lit as well prior to starting when the ignition is energized. I believe that the 02 GM trucks operate the same as the newer ones, which means they have factory antigrind, and will stop engaging the starter when the vehicle is running. I would suggest to just leave it on voltage sensing. In extended crank mode. It sounds to me as if the 555L is either working correctly or you are not on the correct wires, if the 555L was not operating properly your truck would go into long tamper mode and not allow it to start with the key until it has been reset (the 10 minute reference in an earlier post covers this). Good luck. Keep us posted.

I actually went to the DesignTech and the Bulldog security websites. The DesignTech provided me with the correct wire codes and the Bulldog actually provided pictures of the 2002 Silverado wires, etc. I undid the nylon cover over the wires which is located under the dash and connected the following wires; Starter: Thin yellow Ign 1: Thick Pink Ing 2: Thin white ACC: Thick orange - this one is really thick. I grounded the unit to the dash frame. All these wires lead to the plug that is located to the left of the BCM near the driver's side kick panel. Should I use extended crank (50% more) or super crank (100% more)? Are the wires correct? Thanks again, Tony
